That's the thing that gets me. If you get to make your own hate speech, you're going to be first and foremost anti-jew? Holocaust denial and then ease your way forward from there? I'd predict these people likely aren't going to end up pro-Israel if I were a gambler. Seems like it'd be easier to be anti-immigrant first to give a taste for imperialism. Then I'd use racism like a League of Legends player uses flash - strategic, sparing use for scapegoats. Relying too heavily on it feeds white supremacy which, of course, shunts you right back to Hitler. That way more energy is left for privatizing shit and doing intervention in outside countries. Both of these are very lucrative avenues compared to school shootings and Holocaust statistics arguments.

Qanon started well after moot had quit 4chan although I wouldn't be surprised if he were still involved somehow. That one started as a role play similar to other role plays at the time, like I remember CIAanon and a few others, like one guy claimed he was an infiltrator into the DNC and had proof of some plot to sterilize white people. Qanon is just the one that caught on probably because it was more interactive and had a habit of doing "yes and" improv.
